My School just received new Promethean boards and teachers are using MacBook Pro. Some of the laptops have no issue connecting to the board through Airplay. A few of the computers are saying the AirPlay is either disconnected or looking for the Display then OFF.
I followed other post instructions by making sure the laptops are updated and checked the firewall. I've also restarted the computer a few times But still getting the same issue. Some computers are using Catalina and a few are using Mojo. Mirroring is selected.
What do I need to do to get Airplay connected so this problem is fixed ASAP.
